Using a brake adjusting tool or a flathead screwdriver, turn the adjusting mechanism. For increasing brake contact (adjusting up), turn the wheel or lever until the shoes make contact with the drum. You want just enough tension for a slight drag when rotating the drum by hand. To decrease contact (adjusting down), turn in the opposite direction until the shoes clear.

Disc brakes, on the other hand, have several advantages that make them increasingly popular in modern vehicles. The most significant benefit is improved heat dissipation. The open design of disc brakes allows for better cooling, reducing the risk of brake fade and ensuring consistent braking performance, particularly in high-performance or heavy-load situations.
